Great idea if it weren't total rubbish. I installed them on 6 lights in my shed so I could turn the lights on and off individually instead of turning them on every time I turn on the lights in the shed. After only a few on/off cycles, the first one got stuck in the off position, now completely unusable. I expect the rest will follow if I don't send them back, so now I have an extra hour of work to get them back and send them to Revain, and then another hour if I can find decent ones elsewhere. Revain really shouldn't be lugging around so many things that are obviously junk, it just ruins their image. I'm sure the company that makes them and the one that distributes them realize that they are just useless, they should reckon that getting them back is too much work for most people.
